TECHNICAL FIELD

Aspects of this document relate generally to an expandable electrical cord protector.

BACKGROUND

As consumer products have increasingly required electricity to function, the need for a residential room to provide sources of electricity has also increased. However, many living spaces only provide one or two electrical outlets. For this reason, extension cords have become a common solution. Many users have extension cords permanently in use in conjunction with a cord protector to prevent people from tripping on the cord, to keep the cords in place, and to make the cord's appearance more sightly.

However, despite being the solution to one problem, current state-of-the-art cord protectors have some problems of their own. First, most cord protectors are sold in predetermined lengths. While many cords are sold in lengths of 25′, 50′, 100′, etc., cord protectors are often sold in shorter lengths, such as 5′ and 15′. This makes it difficult to completely protect a cord, especially if the cord protectors cannot be connected together.

In addition, residential cord protectors are made from a rubber or soft vinyl material and can therefore crush if enough weight is placed on them. This puts the cord inside of the cord protector at risk. While there are commercial grade cord protectors on the market which are made from rigid materials, these are prohibitively expensive for most homeowners. Thirdly, residential cord protectors are sold in a coil. Users must straighten the cord protector before use, but this is often difficult to do. Many cord protectors are never quite able to remain flat on a surface, and therefore do not effectively eliminate trip hazards and keep the cord in place.

What is needed is a cord protector which can be adjusted to any length, is rigid but inexpensive to make, and can be packaged, transported, and stored without using a coil, thus removing the need for straightening.

DETAILED DESCRIPTION

This document features an expandable electrical cord protector. There are many features of an expandable cord protector disclosed herein, of which one, a plurality, or all features or steps may be used in any particular implementation.

In the following description, reference is made to the accompanying drawings which form a part hereof, and which show by way of illustration possible implementations. It is to be understood that other implementations may be utilized, and structural, as well as procedural, changes may be made without departing from the scope of this document. As a matter of convenience, various components will be described using exemplary materials, sizes, shapes, dimensions, and the like. However, this document is not limited to the stated examples and other configurations are possible and within the teachings of the present disclosure. As will become apparent, changes may be made in the function and/or arrangement of any of the elements described in the disclosed exemplary implementations without departing from the spirit and scope of this disclosure.

FIG. 1 and FIG. 2 depict a first embodiment of an expandable cord protector 10 system. The cord protector 10 has at least one coupler 12 and at least one elongated body 14 with a base 16 and a lid 18. The elongated body 14 may be extruded from a first material. The base 16 has a first end 20, a second end 22 opposite the first end 20, and a channel 24 that extends between the first end 20 and the second end 22. The first end 20 and the second end 22 may each have a cavity 30 longitudinally disposed in the first end 20 and the second end 22. The cavity 30 of the first end 20 may have a first cross section that is the same as a second cross section of the cavity 30 of the second end 22. The expandable cord protectors 10 may be formed through extrusion, establishing a consistent channel 24 and cavity 30 extending from the first end 20 of the expandable cord protectors 10 to the second end 22.

As shown in FIG. 3, the coupler 12 has a leading end 34 and a trailing end 36. The leading end 34 of the coupler 12 may be sized and shaped to mate with the cavity 30 of the first end 20 of the elongated body 14. The trailing end 36 of the coupler 12 may be sized and shaped to mate with the cavity 30 of the second end 22 of the elongated body 14. When two elongated bodies 14 are joined together by a coupler 12, the leading end 34 of the coupler 12 is coupled with the first end 20 of a first of the two elongated bodies 14 and the trailing end 36 is coupled with the second end 22 of a second of the elongated bodies 14. This pattern may be followed to join additional elongated bodies 14 and form an elongated cord protector system. For example, to join a third elongated body 14, the first end 20 of the second of the two elongated bodies 14 is coupled with the leading end 34 of a second coupler 12 and the second end 22 of the third elongated body 14 is coupled with the trailing end 36 of the second coupler 12. In this manner, any length of cord may be protected by changing the number of cord protectors 10 that are used.

FIG. 4 depicts an end view of the elongated body 14. The channel 24 may have two top edges 26 and two ridges 28, with each ridge 28 adjacent one of the two top edges 26. The lid 18 may have one or more grooves 32. Each of the grooves 32 may be sized and shaped to receive one of the ridges 28. The lid 18 is configured to insert into and cover the channel 24. The lid 18 may insert into the channel 24 by sliding into the channel from either the first end 20 or the second end 22 of the base 16, or by snapping the lid 18 directly downward against the channel 24 with both grooves 32 of the lid engaging respective ridges 28 of the channel 24. In embodiments with ridges 28, the ridges 28 may slide or snap into one of the grooves 32, thus securing the lid 18 inside of the channel 24.

The base 16 may further include an optional a gripping material 38 coupled to the bottom surface 40 of the base 16. The gripping material 38 is configured to attach the cord protector 10 to a surface on which the cord protector 10 rests. Without limitation, the gripping material 38 may be a hook-type fabric that attaches to carpet, an adhesive configured to grip a hard surface, such as double-sided tape, a rubberized coating to increase friction between the bottom surface 40 of the base 16 and the surface on which the cord protector 10 rests, or some other friction enhancing material known in the art.

FIGS. 5-8 depict a second embodiment of an expandable cord protector 50. The cord protector 50 has a first end 52, a second end 54, and an elongated body 56. The first end 52 has a protrusion 58 with a lip 60 extending outward from the protrusion 58 (see FIG. 7 and FIG. 8). The protrusion 58 may have a U-shaped cross section (see FIG. 7). The second end 54 has a cavity 62 that is sized and shaped to receive the protrusion 58. Within the cavity 62 there may be a groove or recess 64 that is sized and shaped to receive the lip 60 of the protrusion 58 (see FIG. 8). Two cord protectors 50 may be coupled together by inserting the protrusion 58 into the cavity 62. The lip 60 interlocks with the groove 64, securing the two cord protectors 50 together (see FIG. 8). This may be implemented with any number of cord protectors 50, thus enabling a user to use the cord protector 50 to protect any length of cord.

FIG. 9 depicts a cross sectional view of the elongated body 56. The elongated body 56 extends between the first end 52 and the second end 54. The elongated body has a cord track 66, a hinge 68, such as a living hinge 68, and a lid 70. The cord track 66 provides a space in which cords can rest. The cord track 66 has a base 72, a first track wall 74, and a second track wall 76. The first track wall 74 and the second track wall 76 both extend upward from the base 72, and are spaced apart to allow at least one cord to rest between the first track wall 74 and the second track wall 76. Like the first embodiment, the embodiment with the living hinge may be manufactured through extrusion.

The hinge 68 is coupled to the base 72 adjacent the point where the first track wall 74 extends upward from the base 72. The hinge 68 may be a living hinge. The lid 70 may be separately attached to the hinge 68, or may be extruded or otherwise molded to form the lid 70 and the base 72 as a single, integral, common material piece. However it is formed, the lid 70 is configured to rotate about the hinge 68 to cover the cord track 66. The lid 70 has a lid latch 78. The base 72 has a base latch 80 adjacent the point where the second track wall 76 extends upward from the base 72. The base latch 80 is configured to releasably couple with the lid latch 78 of the lid 70.

Like with all previous embodiments, the base 72 may have a gripping material 82 coupled to the bottom surface 84 of the base 72. The gripping material 38 is configured to attach the cord protector 10 to a surface on which the cord protector 10 rests. Without limitation, the gripping material 38 may be a hook-type fabric that attaches to carpet, an adhesive configured to grip a hard surface, such as double-sided tape, a rubberized coating to increase friction between the bottom surface 40 of the base 16 and the surface on which the cord protector 10 rests, or some other friction enhancing material known in the art.

With any of the embodiments disclosed herein, the cord protector 10, 50, 56 may be of a unitary construction, with all components being formed together at the same time in one manufacturing process, such as through extrusion or injection molding. The cord protector 10, 50, 56 may be constructed of a rigid material, sufficiently rigid to support the weight of a person walking on or a vehicle rolling across the cord protector.
